Purpose:
The instrument is designed and made as per the National Standard GB/T11143 “Test Methods for Water Content of Liquid Petroleum Products (Karl Fischer Methods)” and ASTM D 1744. It is suitable to determine water content in the liquid petroleum products by titration using Karl Fischer reagent. Adopt a microprocessor for control, so it has characteristics of rapid determination speed, high precision, LCD display, and automatic print. It also has function of self-diagnostics, menu selection. It is a multifunctional, convenient, and automatic analysis instrument.
